How does one get a pic onto a post?

Hey you guys!!I finally started building out my tank after many revised plans(the final ones didn't work in the end anyways-the glass cutter drilled my tank wrong-uggg!) But after a few tears and fits...Ah..I'm back on track..but now, how does one post a few pics for you guys to see and give suggestions? Oh, the best of plans can go awry, but a herper(especially-a PDFrogger)always comes a leapin back :-)
